Hauv kev siv dav dav, symmetry feem ntau yog hais txog tomirror lossis reflective symmetry ; uas yog, ib txoj kab (hauv 2-D) orplane (hauv 3-D) tuaj yeem kos los ntawm ib qho khoom xws li ob qho tib si yog daim iav duab ntawm ib leeg. Ib daim duab peb sab isosceles thiab ahuman ntsej muag yog piv txwv.
Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog 4 hom symmetry?
Cov plaub lub ntsiab hom ntawm no symmetry yog txhais, rotation, reflection, thiab glidereflection.
Tsis tas li ntawd, hom symmetry hauv lej yog dab tsi? Reflectional symmetry , linear symmetry , iav symmetry , iav-duab symmetry , los yog ob tog symmetry yog symmetry nrog rau kev xav. Thusa square muaj plaub axes ntawm symmetry , vim muaj plaub txawv txoj kev los quav nws thiab muaj cov npoo allmatch.
Yog li ntawd, dab tsi yog symmetry nyob rau hauv lub neej txhua hnub?
Symmetry feem ntau pom txhua hnub los ntawm cov neeg ntawm txhua lub hnub nyoog hauv qhov xwm txheej. Symmetry uas peb pom txhua hnub Hauv qhov xwm txheej feem ntau yog Bilateral Symmetry . Qhov no txhais tau hais tias ob qho tib si ntawm ib qho khoom yog daim iav duab ntawm ib leeg.
Nyob qhov twg symmetry?
Symmetry yog pom nyob rau hauv txhua hom kev tsim. Nws yog pom hauv luam ntawv thiab hauv web.

Ib qho piv txwv ntawm ib qho alloy yog dab tsi?
Ib qho piv txwv ntawm cov hlau yog sib xyaw ntawm cov hlau thiab hlau. Ib qho piv txwv ntawm cov hlau yog cov tin hauv qhov sib xyaw ntawm tooj liab thiab tin uas ua rau tooj liab. Lub alloy yog ib qho fusion ntawm ob lossis ntau dua hlau lossis cov hlau uas tsis yog hlau. Ib qho piv txwv ntawm cov hlau yog tooj dag, uas yog tsim los ntawm tooj liab thiab zinc
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
